I originally looked on wikipedia for the history of lithium, and how it was first isolated. It says, "William Thomas Brande performed electrolysis on lithium oxide", but without any specifics, as in chemical equations, voltage potentials, apparatus, and if the salt was molten or not. Now, the reason I am interested, is because I *think, that William Thomas Brande isolated lithium by dissolving lithium oxide in a polar aprotic solvent; thus allowing electrolysis without fusing the lithium oxide. Anyway, back to the point, I cannot seem to find the specific's for Brande's process anywhere. On the internet, I only find the same sentence repeated on many websites, and I …

Some one asked me this (above)question and thats what i had to say about it; HF is a molecule in which F is more electronegative than H, that is, F has a higher tendency to attract electron than H, so the cosequence is that this molecule has a dipole, negative over F and positive over H. B:--> H--------F --------> BH+ + F- (I hope you can imagine the arrows and dipoles over HF molecule) A nucleophile attach the H dipole and the bond breaks heterolytically so that both electron in the bond go to the same atom in this case to flourine. I was going fine until here and got stuck as to how to explain further. I will appreciate any comments from…

Is this the best way to seperate the two salts? heating to 100C letting it cool to ~50C then filtering?

HELP!! I have alluminum oxide stuck in my new iron crucible and I have no idea how to get it out. Can somebody tell mehow to get rid of the aluminum oxide without destroying the iron crucible? maybe some kind of acid?

Hi, My goal is to make sodium metal throught he electrolysis of molten sodium. I plan to use a sodium chloride/ calcium chloride mix to lower the melting point. Or would sodium hydroxide be easier? I was going to build and use a Down's cell or something like it (info: http://en.wikipedia.org/wiki/Downs_Cell) over a waste oil powered furnace to keep the salt molten. Is there an easier way to construct a cell? I heard about using an iron crucible as one electrode and a rod as the other but if any of the chlorine gas comes in contact with the sodium I'll have an explosion right? Also, would it be easier to make sodium through the thermal reduction of sodium carbonate with…

My dad said for me to look this up can anyone explain the process for me.

My final experiment for the 9th grade this morning in the elemental synthesis set involved me making some chlorine (to demonstrate synthesis of NaCl using pure sodium metal; magnesium chloride, etc.) I was too busy to have much time to prepare so, remembering that mixing glass cleaning products (ammonia) with household bleach, I borrowed some bleach from home. Using a dropper funnel and filter flask with a bubbler and some 250mL Ehrlenmeyer flasks to collect it, I began ... and it was pathetic. I ended up using about 100 mL of bleach in the reaction flask and added around 100 mL of 30% ammonia solution. I got a grand total of 1 flask of chlorine, about 250 mL. Doesn'…

I wish to collect H2 gas in a safe and cost effective way. One way I read was to react Zn metal with acid ( HCl or H2SO4). Where wil I be able to get all the stuff from? What would be the best way to store H2 gas. The reason I want to produce H2 is, I want to see, if I BUBBLE H2 gas thru water, how does its ORP (Oxidantion Reduction Potential) change. I have read that, when H2 gas is bubbled through water, the ORP of water become highly negative as H2 gas is a strong REDUCTANT ( aka anti-oxidant). I want to prove this with my experiment. Any ideas?

I want to make chlorine dioxide. I dont have any sodium chlorite but I do have potassium chlorate. perhaps if i were to carefully combone very small amounts of sodium or potassium chloride with potassium chlorate it'd give off the dioxide? It seems like it'd be a feisty reaction, though... it might just catch fire to the dioxide immediately...

quote from http://www.geocities.com/CapeCanaveral/Campus/5361/kno3/ammnit.html You can scale the following up or down. Take 760cc (760g) of water and heat to about 50C. To this water add 3 mole (223.5 grams) of your recrystalized and dried KCl and dissolve. Add 480grams of your Ammonium Nitrate solution. You will now have one liter of water with 3 moles of Ammonium Nitrate and 3 moles of KCl dissolved in it. Note: You won't actually have a liter of SOLUTION as dissolving the salts in the water will increase the volume. If you are using pure Ammonium Nitrate (you did not bother with the 50% solution above) you should take one liter of water, 223.5grams KCl and …

can u make kno3 from urea and nh4no4 and if u can how would i go by doin it

There's one experiment (posted somewhere on this forum) involving burning seaweed to ash, boiling the ashes with water, filtering and collecting the filtrate, and adding to it a solution of acidified hydrogen peroxide. I've tried the lab many times with careful attention to precision, yet each time, I failed miserably. If anyone is familiar with the extraction process (or any other method for isolating iodine) and can lead me through it, that would be great. Thanks

Greeting ladies and gents- perhaps i can get a good straight answer here! Ive been restoring motorbikes, and have come across the question of plating the occasional . Im after bright finishes in copper zinc or nickel (Chromium is far too dangerous)- but the COSHH info on Nickel especially seems to rule that out. Ironic as copper plating is a standard school experiment! Im thinking of using a very low impact method, to get even mirror coats- even using drycell battery packs over many days if necessary. And yes this will be done in a well ventilated shed at outside temperature, to minimise the effect fo gases of any kind, using ammoniacal/metal sulphate solutions as opp…

I dont own one of these (WI) but was wondering anyone out here knows anything about them. A WI is basically a electrical device, which uses the concept of Electrolysis of water. The Anode and Cathode are separated by a porous membrane. So all the cations move towards Cathode(-ve electrode) and Anions move towards Anode (+ve electrode) Hydrogen gas is produced at the cathode. It is recommended that this hydrogen rich water is the best anti-oxidant and should be drunk to fight oxidative stress. This H2 rich water will have a -ve ORP. It is the alkaline water. But what about all the anions on the other electrode. We are basically wasting all those anions. ( Chlorides, …

I am trying to make ozone to react with chlorine and make chlorine mono/di/tri oxide. I was wondering if there are any better ways to make ozone besides arching extremely high voltages. Or can I use some other oxidizer like nitrous oxide or something to oxidize the chlorine. Thanks!

Well I've been making rust for use and thermte and I found this way of makingiron oxide without using electrolysis. But what does it yield? H2O2+NaCl+Fe= For some reason I keep thinking that I made chlorine gas. Which is not good. I'm pretty sure it would make hydrogen-chloride I was running this experiment outside, but whne the hydrogen peroxide began to froze I brought it inside and removed the iron I was using, but it still continued to bubble. I left it in the house overnight (it's 4am now) without thinking that might be making chlorine. About 20 minutes ago, I dumped the solution out outside. I still can't stop thinking about it though.

What would be the good source to obtain Zn metal? where to buy ZINC? thanks..

Hi, I am interested in doing electrolysis of water. Where can I buy Pt electrodes? Do they sell it somewhere? I am interested in producing H2 gas by electrolysis.

Hi, I'm new here and I was wondering if anyone knows how dangerous arsenic is in a domestic garden environment? Would levels of 160 ppm in the soil make growing vegetables dangerous? Does anyone know how much of that arsenic is likely to move in the soil and water if the soil is disturbed? If the soil was moved a lot during construction could the arsenic move in any dust produced and how dangerous would that be to human health? I have no scientific background other than basic soil science in horticulture and I am finding it hard to get much information on contaminated ground. Thanks

I wanted to get a higher concentration of hydrogen peroxide, so I decided to get it from glow sticks. The H2O2 is supposed to be in the glass vial and the phenyl w/ the dye is supposed to be surrounding it, but it seems that in the case of my glow stick, it's the other way around. Ether that, or the dye is mixed with the H2O2. I have not broken open the glass vial yet. The solution that was surrounding it is clear with an odor like rubbing alcohol. Any ideas on which is which? I'd hate to have the H2O2 have a dye mixed with it. Thanks, Kenneth Anderson

Which would be the more likely result of passing gaseous iodine over sodium amide: NaNH2 + 2I2 -> 2HI + NaNI2 or NaNH2 + I2 -> NaI + NIH2 The first reaction would produce a much more interesting product, NaNI2, the second seems like a way a good way to inhale a poisonous explosive…

I was walking ... ok you dont need to know the details. I have a jar of metalic powder that i found in a garage. It was used to make reflective paint so i asumed Al ... So to test my theory i put a pinch into HCl but nothing happened so now i am lead to believe that it is not Al. I tested it with a magnet. Its not magnetic. It is grey in colour and is quite heavy (i will work out its density and post it later) Any suggestions as to how i can find out what it is ??? Much appreciated

Hey, I was wondering what the results of aqueous FeSO4 + KMnO4 under acidic conditions would be, and also what colour changes would be observed. I know FeSO4 is initially green, and KMnO4 is purple, but i'm not sure of the changes in oxidation states that would occur. Would go to Fe2O3 + MnO2, therefore turning a blackish brown? but then the K is not accounted for.

i know the half eqt for it when it is acidic. but would anybody like to tell me the one when it is alkaline? which one is a stronger O.A.? and one more question, while we are using the half eqt to make up the whole ionic eqt, sometimes we will cancel out the element which exist in both side i.e. 3A+ 6P ---> 3A+5Y but does it mean that it doesn't require in the reaction? thank you

I know that you can buy sodium bromide at a store, but i just got some bromine so it would be cool if i could do this. So would sodium bromide be made, if I heated bromine and sodium chloride together.
